Son auteur (= Marqe) vivait au 1er siècle avant l'ère chrétienne, selon l'opinion des Samaritains.
The footnote is to this source is M Heidenheim, der Kommentar Marqas, des Samaritaners, Weimar, 1896, Biblioteca Samaritana, III, p. viii. A very rare book it would seem. There are others who have intimated such a date for Marqe - Brodie in A Samaritan Philosophy. But I am curious whether Heidenheim actually met Samaritans who told him this information or whether he is speaking about Samaritan written sources. I don't know of any which say this. All of which makes it quite intriguing.
